Introduction
• Nanotechnology is derived from the greek word “dwarf”.
• Nanotechnology is the engineering of functional systems at the molecular scale.This covers both current work and concepts that are more advanced.
• Nanotechnology refers to the projected ability to construct items from the bottom up,using techniques and tools being developed today to make complete,high performance products
APPLICATIONS OF NANOTECHNOLOGY
ELECTRONICS
ENERGY
AUTOMOBILES
SPORTS AND TOYS
TEXTILES
COSMETICS
DOMESTIC APPLIANCES
BIOTECHNOLOGY AND MEDICAL FIELD
SPACE AND DEFENSE
ELECTRONICS
• THE COATINGS USED ON TV SCREENS IS MADE UP OF NANOPARTICLES FOR THE BETTER PROPERTIES IN TERMS OF COLOUR QUALITY.
ENERGY
• NATURAL ENERGY RESOURCES LIKE COAL,NATURAL GAS,OIL ARE LIMITED AND DEPLETING VERY FAST.
• THE FUTURE GENERATIONS ARE LOOKING FOR ALTERNATIVE ENERGY RESOURCES LIKE SOLAR ENERGY OR HYDROGEN BASED FUEL,AND THE SCIENTISTS ARE HOPING TO MAKE EFFICIENT SOLAR CELLS USING NANOMATERIALS.
AUTOMOBILES
• A SIMPLE CAR IS MADE UP OF LARGE NUMBER OF PARTS AND MATERIALS WHOSE BODY AND VARIOUS STRUCTURAL PARTS ARE MADE UP OF STEEL,SOME ALLOYS,RUBBERS PLASTICS.
• WHEREAS STEEL DOES NOT PROVIDE EXCELLENT MECHANICAL STRENGTH, SO BY USING NANOPARTICLES WE CAN REPLACE NANOTUBE COMPOSITES WITH STEEL.
SPORTS AND TOYS
• TENNIS BALLS USING NANOCLAY ARE ABLE TO FILL PORES IN BETTER WAY AND TRAP THE AIR PRESSURE INSIDE FOR INCRESING THE LIFE OF BALL.INTERNATIONAL ORGANIZATIONS HAVE ALSO ACCEPTED SUCH TYPE OF BALLS FOR THEIR TOURNAMENTS.
• NOWADAYS NANOTECHNOLOY BASED MOTORS ARE USED BY TOY INDUSTRY FOR MAKING THEM SMOOTH AND SWIFT.
TEXTILE
• THERE ARE SOME CLOTHES PRODUCED WHICH WOULD GIVE PLEASANT LOOK OF SYNTHETIC FIBREAND ALSO COMFORT OF COTTON.
• SPECIAL THREADS AND DYES ARE USED IN TEXTILE INDUSTRY ARE PRODUCTS OF NANOTECHNOLOGY.
• THESE CLOTHES DO NOT REQUIRE IRONING NOR FREQUENT CLEANING.
COSMETICS
• ZINC OXIDE AND TITANIUM OXIDE NANOPARTICLES OF FAIRLY UNIFORM SIZE ARE ABLE TO ABSORB ULTRAVIOLET LIGHT AND PROTECT THE SKIN.
DOMESTIC APPLIANCES
• USE OF SILVER NANOPARTICLES IS MADE IN REFRIGERATORS,AIR PURIFIERS
• SILVER NANOPARTICLES HAS A LONGER TIME OF ANTIBACTERIALL PROPERTY.
• FOOD IN REFRIGERATORS CAN REMAIN FRESH AND PREVENT FUNGAL GROWTH FOR LONGER TIME THAN ORDINARY REFRIGERATORS.
BIOTECHNOLOGY AND MEDICAL FIELD
• Medical nanotechnology also makes cell repair on a molecular level possible, and provides a number of opportunities for medication administration. Drugs developed through nanotechnology could directly penetrate cells, for example, or nanoparticles could be designed to target cancer cells, delivering medication or providing a focal point for radiation. Medical nanotechnology can also be used to make biosensors which can be implanted into patients for monitoring, along with medical devices which are designed to be permanently implanted such as pacemakers.
SPACE AND DEFENSE
• Including layers of bio-nano robots in spacesuits. The outer layer of bio-nano robots would respond to damages to the spacesuit, for example to seal up punctures. An inner layer of bio-nano robots could respond if the astronaut was in trouble, for example by providing drugs in a medical emergency.
Advantages
• Nanotechnology can actually revolutionize a lot of electronic products, procedures, and applications. The areas that benefit from the continued development of nanotechnology when it comes to electronic products include nano transistors, nano diodes, OLED, plasma displays, quantum computers, and many more.
• Nanotechnology can also benefit the energy sector. The development of more effective energy-producing, energy-absorbing, and energy storage products in smaller and more efficient devices is possible with this technology. Such items like batteries, fuel cells, and solar cells can be built smaller but can be made to be more effective with this technology.
• Another industry that can benefit from nanotechnology is the manufacturing sector that will need materials like nanotubes, aerogels, nano particles, and other similar items to produce their products with. These materials are often stronger, more durable, and lighter than those that are not produced with the help of nanotechnology.
Disadvantages
• You will also find that the development of nanotechnology can also bring about the crash of certain markets due to the lowering of the value of oil and diamonds due to the possibility of developing alternative sources of energy that are more efficient and won’t require the use of fossil fuels. This can also mean that since people can now develop products at the molecular level, diamonds will also lose its value since it can now be mass produced.
• Atomic weapons can now be more accessible and made to be more powerful and more destructive. These can also become more accessible with nanotechnology.
• Since these particles are very small, problems can actually arise from the inhalation of these minute particles, much like the problems a person gets from inhaling minute asbestos particles.
• Presently, nanotechnology is very expensive and developing it can cost you a lot of money. It is also pretty difficult to manufacture, which is probably why products made with nanotechnology are more expensive.
Future use of Nanotechnology
• Nanotechnology is expected to have an impact on nearly every industry. The U.S. National Science Foundation has predicted that the global market for nanotechnologies will reach $1 trillion or more within 20 years. The research community is actively pursuing hundreds of applications in nanomaterials, nanoelectronics, and bionanotechnology.
Conclusion
• Nanotechnology offers the ability to build large numbers of products that are incredibly powerful by today's standards. This possibility creates both opportunity and risk. The problem of minimizing the risk is not simple; excessive restriction creates black markets, which in this context implies unrestricted nanofabrication. Selecting the proper level of restriction is likely to pose a difficult challenge.
